The incident occurred just before 6:45 p.m. after the deputy and a reserve deputy stopped a black Chevrolet Silverado for running a red light at Sprinkle and Lake Street, Matyas said.

Matyas said the two were approaching the vehicle on foot when someone in the truck fired several rounds at the deputy from the truck's driver's side window.

The deputies both returned fire and shot several rounds at the truck, which fled east on East Michigan Avenue, the undersheriff said.

Matyas said one of the rounds grazed the deputy's arm. The reserve deputy was not hurt.

Matyas said investigators don't know, at this point, whether the suspect was wounded during the exchange of gunfire.

About an hour after the incident, deputies found the Silverado abandoned not far from the scene near the intersection of Collette Avenue and Electra Street. Deputies said several rounds from a 9 mm handgun were found inside the truck.

Matyas said police canines were doing a track from the abandoned truck to try to find the suspected shooter.

As of about 9:15 p.m. Friday, Matyas said investigators have persons of interest they are seeking for questioning in connection with the incident.
